a doberman or a springer spaniel?

I love the look of Dobermans and find them so impressive. (Plus I am biased towards dogs that are black with tan points haha). I am more familiar with them though I’d love to see springer spaniels working. The one I knew at the kennel was sooo hyper but I’d have to meet more to get a better opinion. I am always super fascinated watching dogs doing what they are bred to do though.
